hobbit-alert.cfg: grouping recipients using macros

["Haertig, David F (Dave)" <haertig (at) avaya.com>]

In the hobbit-alerts.cfg file, can you group recipients using macros?
The help file only has examples for directives that use equal signs
(e.g., HOST=%$MYHOSTS).  The MAIL and SCRIPT directives have their first
parameter defined as "a recipient", which doesn't necessarily imply that
they'll accept a comma seperated list of recipients (although I expect
they might well do this).
 
Example:
 
$JOHN=john (at) mycompany.com
$FRED=fred (at) mycompany.com
$JANE=jane (at) mycompany.com
 
$MYGROUP=$JOHN,$FRED,$JANE
$OTHERGROUP=$JOHN,$JANE
 
HOST=whatever SERVICE=whatever
    MAIL $MYGROUP REPEAT=2h
 
HOST=somethingelse SERVICE=somethingelse
    MAIL $OTHERGROUP REPEAT=2d
